WIRE-TWISTING IMPLEMENT.

Specification of Letters Patent.

Patented Dec. 6, 1910.

Application filed March 9, 1910. Serial No. 548,232.

To all whom "it may concern:

Be it known that I, AUGUST KAsI-An, a citizen of the United States,residing at Shiner, in the county of Lavaca and State of Texas, haveinvented a new and useful Wire-Twisting Implement, of which thefollowing is a specification.

This invention relates to wire twisting implements, and the object ofthe invention is to provide a tool of simple construction by which themanufacture of woven wire baskets may be facilitated. This object isattained by the use of the device illustrated in the accompanyingdrawings, and the invention consists in certain novel features thereof,as will be hereinafter first fully de scribed and then more particularlypointed out in the appended claims.

In the accompanying drawings, Figure 1 is a perspective view of a toolembodying my invention showing the same arranged to twist a pair ofwires. Fig. 2 is a view showing parts of the tool in longitudinalsection and other parts in side elevation. Fig. 3 is an enlargedtransverse section on the line 3-3 of Fig. 2. Fig. 4 is a detail endView of the bit. Fig. 5 is a detail plan view of the active end of thebit.

In carrying out my invention, I employ a hollow handle 1 having openends and provided at or near its front end with guides 2 which, in thepresent instance, are illustrated as consisting of rollers 3 mounted onpins a, secured rigidly within the wall of the handle. These rollers arespaced slightly apart and a spirally twisted shank 5 is engaged betweenthe same so that if the handle be moved longitudinally with respect tothe shank, the said rollers will ride upon the shank so as to impart arotary motion to the same and to the bit 6 secured to the front endthereof. In order to limit the movement of the parts and to preventdisengagement of the same, stops 7 of any desired or convenient form areprovided at the rear end of the shank, which are adapted to impingeagainst the guides 2 and thereby arrest the movement of the handle inthe operation of the tool. The device may be thus made to automaticallydetermine the length of the twist imparted to the wires by the tool, anda series of tools having shanks of different lengths may be provided inorder that a twist of any desired length may be imparted to the wires.

'To the front end ofthe spiralshank 5, I

secure the bracket or jaws 8 which are provided with lateral lips orstops 9 adapted to engage the front end of the handle and therebyprevent the handle being carried so far forward as to be released fromthe shank. Between the jaws 8, I secure the bits (3 and the ends of thejaws are provided at their o posite sides with lugs or teeth 10 adaptedto engage the opposite sides of the bit and thereby prevent pivotalmovement of the bit upon the securing bolt 11 by which it is heldbetween the aws.

The bit consists of a substantially rectangular body having its outerend shaped to present the wire-engaging lips 12. These lips convergefrom the opposite sides of the bit toward the free end of the same, and,as shown in Figs. at and 5, are in the form of oppositely-disposed hooksadapted to engage the diverging strands of wire, indicated at 13, sothat when rotary movement is imparted to the bit from the shank,thewires will be caused to wrap around each other and thereby produce thespiral twist 14. Each of the ribs or hooks 12 projects forward from awall 15 which extends obliquely from the side. of the bit toward the endof the same, and the edge of the projecting portion rises above the bodyof the same substantially parallel with the said inclined wall andthereby forms a groove 16 in which the wire will be seated, as clearlyshown in Fig. 1. The groove on one side opens upwardly and on the otheropens downwardly.

The handle is substantially cylindrical except at the front end where itis enlarged in diameter to there reinforce it, and this enlarged endslopes or expands rearwardly. The handle is of such length as toentirely house the spiral portion of the shank when the latter is in theretracted position, and

this long handle and also the expanded front end serves to direct longwires away from the operator, so that the twisting of the wires may beperformed without danger of the long ends striking the operator.

In operating my improved tool, it is necessary merely to engage the bitwith the diverging wire strands, as shown in Fig. 1, and then exert aslight pull on the handle sufficient to move the same longitudinallytoward the rear end of the shank. The shank will thus be rotated so thatthe bit will be caused to twist the wire strands around each other, aswill be readily understood, and this movement will be continued untilthe guides 2 at the front end of the handle impinge against the stops 7atthe rear end of the shank, it being understood that the lips 12 engagethe wire strands with sutiicient firmness to prevent the bit being drawntherefrom when movement is imparted to the handle. The wire strands aresecured together to form the bottom of the basket or the initial loop ofa wire fence fabric or other woven wire fabric in any desired manner,and the branches of the doubled wire are engaged by the bit so that thetwisting of the wires and the production of the finished fabric may berapidly accomplished with very little labor.

From the foregoing description, taken in connection with theaccompanying drawings, the advantages of the construction and of themethod of operation will be readily apparent to those skilled in the artto which the invention appertains, and while I have described theprinciple of operation of the invention, together with the device whichI now consider to be the best embodiment thereof, I desire to have itunderstood, that the device shown is merely illustrative, and that suchchanges may be made when desired as are within the scope of the claimsappended hereto.

Having thus described the invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A wire twisting tool provided with a handle, a twisting head, and aspiral shank for the twisting head, said handle being of a length toentirely house the twisted end of the shank when the latter is in the retracted position.

2. A wire twisting tool provided with a handle, a twisting head, and aspiral shank for the twisting head, said handle being of a length toentirely house the spiral end of the shank when the latter is in theretracted position, the handle being of tubular form with the endthrough which the shank moves reinforced.

3. A wire twisting tool provided with a handle, a twisting head, and aspiral shank for the twisting head, said handle being of a length toentirely house the spiral portion of the shank when the latter is in theretracted position, the handle being of tubular form with the endthrough which the shank moves reinforced, and expanding rearwardly.

f. A wire twisting tool provided with an elongated tubular handle, aspirally twisted shank adapted when retracted to have its twistedportion entirely housed in said handle, means in the handle forimparting r0- tative movement to the ,shank on the movement of thelatter longitudinally of the handle, and a socket member fast to thefront end of the shank.

5. A wire twisting tool provided with an elongated tubular handle, aspirally twisted shank adapted when retracted to have its twistedportion entirely housed in said handle, means in the handle forimparting rotative movement to the shank on the movement of the latterlongitudinally of the handle, a socket member fast to the front end ofthe shank, and a stop member carried by the shank in predeterminedposition thereon.

6. In combination with the hollow handle, rollers mounted on pinssecured within the wall of the handle, said rollers being spaced apart,a spirally twisted shank engaged between the rollers, and stops providedon the ends of the shank.

7. A wire twisting tool comprising a twisting bit, a socket memberadapted to receive said bit, a spirally twisted shank fast to the socketmember, and an elongated handle of greater length than the twistedportion of the shankand adapted to completely house the same when in theretracted position, said handle being provided with guiding means forthe shank to impart rotative movement thereto on the longitudinalmovement of the shank.

8. A wire twisting tool comprising a twisting bit, a socket memberadapted to receive said bit, a spirally twisted shank fast 7 to thesocket member, and an elongated handle of greater length than thetwisted portion of the shank and adapted to completely house the samewhen in the retracted position, said handle being provided with guidingmeans for the shank to impart rotative movement thereto on thelongitudinal movement of the shank, the handle having the end receivingthe shank enlarged in diameter and externally expanding toward the otherend of the handle, and the handle eX- cept at the enlarged end beingsubstantially cylindrical throughout. 4

9. A wire twisting tool comprising an elongated handle, a spirallytwisted shank having the spiral portion when retracted entirely housedwithin the handle, means at the end of the handle into and out of whichthe shank moves for imparting rotative movement to the shank, meansoarried by the shank for determining the distance of projection of theshank from the handle, and a socket member for a twisting tool carriedby the shank, said socket mem ber comprising jaws each of which isformed at the rear end with a lateral lip adapted to engage thecorresponding end of the handle member to limit the ret-raetive movementof the shank.

In testimony, that I claim the foregoing as my own, I have heretoaffixed my signature in the presence of two witnesses.
